Long-term clinical outcomes of innervated digital artery perforator flap in the treatment of fingertip injuries

A case of 40-year-old female with melanoma in situ on her left index finger is presented. When treating melanoma in situ, it is recommended to have 3 mm margin and to include subcutaneous fat layer for resection of the tumor. To reconstruct the fingertip with the exposed distal phalanx, we used digital artery perforator flap. Since the resection of melanoma in situ in the appropriate manner would result in low risk of recurrence of the tumor, unlike melanoma of more deeply infiltrating types, it is important to use flaps which are easy to raise, functionally superior, and cosmetically excellent, The drawbacks of using digital artery perforator flap is that the operator is not able to tell if the flap includes the perforator until the flap is raised, since there is a risk of damaging the perforator when trying to expose it to visually confirm that it is included in the flap.

Little Finger

An ulnar digital artery perforator flap has been used for little finger reconstruction. The flap is found to have a reliable blood supply, it is being perfused by a constant sizeable perforator. This paper helps describes a case report of a patient with injury to little finger with exposed bone for which a ulnar digital artery perforator flap was done. The position of the perforator was confirmed intraoperatively by an exploratory incision before committing to the distal incision. The flap used to cover the flexor aspect of the little finger has given good result.

Abstract Background When restoring the appearance and function of the fingers, hand surgeons face a challenge in choosing a suitable surgical method to repair finger skin defects. Methods In this study, we designed a long elliptical flap based on a propeller perforator flap and located slightly toward the dorsal lateral aspect of the finger. The flap with a pedicle consisting of the dorsal perforator of the distal digital artery and dorsal digital artery perforator chain is rotated to cover a large wound on the distal end. From December 2014 to December 2017, 10 patients with finger soft tissue defects were treated with the propeller perforator flap described in this study. Results All flaps survived after surgery, and 2 had a transient venous congestion. After a follow-up period of 3 to 12 months, the static two-point discrimination of the flap was 8.06 ± 1.75 mm, and the range of motion was 149.4 ± 12.9°. This designed flap can span several angiosomes supplied by the perforators. Due to the inclusion of a vessel chain between the dorsal digital artery perforators, the length-to-width ratio of the flap can be up to 3:1. Conclusions This technique increases the size of flap that can be harvested safely while retaining a reliable blood supply. The present study describes a new method for repairing soft tissue defects of the finger by using the technique of propeller perforator flaps based on dorsal digital artery perforator chains. Trial registration The registration number of this study is ChiCTR1800014588; it has been retrospectively registered with Chinese Clinical Trial Registry (chictr.org.cn), 18/11/2019.
